Few cross-sectional studies report iron deficiency (ID) prevalence in women of different race/ethnicity and ages US or Canada.We evaluated screening observations on who participated between 2001-2003 a cross-sectional, primary care-based sample adults ≥25 y whose were complete: race/ethnicity; age; transferrin saturation; serum ferritin; HFE p.C282Y p.H63D alleles. We defined ID using stringent criterion: combined saturation <10% ferritin <33.7 pmol/L (<15 μg/L). compared subgrouped by age determined associations to overall, 25-44 with without self-reported pregnancy.These 62,685 included 27,079 whites, 17,272 blacks, 8,566 Hispanics, 7,615 Asians, 449 Pacific Islanders, 441 Native Americans, 1,263 participants other race/ethnicity. Proportions higher Hispanics blacks than whites Asians. Prevalence was significantly greater 25-54 all groups ≥55 corresponding In y, did not differ across ID, regardless race/ethnicity, subgroup, pregnancy.ID Hispanic black white Asian y. pregnancy.
